You're obsessed with which round they were KO'd in. The fact of the matter is that Machen was KO'd by Johansson. He doesn't get a "fluke pass" because it's Johansson most impressive and/or quickest KO. The result is the result. winning results against nobodies are irrelevant. No one cares about Bruno's 1st round KO of John Emmen or Chuck Gardner, and a bunch of other bums I can't remember. That's not how we measure a fighter's caliber. The fact is Johansson KO'd the #1 contender and the world champion (neither had been KO'd before) in back-to-back fights at his peak. The only logical conclusion to draw is that Johansson in 1958-'59 was a world class operator and a big puncher. It's absurd that you engage in weird mental gymnastics to try to disprove that obvious point. I have no idea what "white hope as power puncher" means. His knockouts of Machen and Patterson are his best. He also KO'd the best fighters in Europe. He was known for his right hand punch.
